5 Claims. (Cl. l2- 18)V This invention relates to improvements inappliances and methods for installing plates of structural material, forinstance, glass, on surfaces to be covered by such material.

One object of the invention is to provide a method nof applying platesof structural material to irregular surfaces, whereby the material willpresent a uniform, level surface when completed, regardless of thenumber of plates used therein.

`Another object is to provide an appliance by which a number of platesof structural material can be installed on a surface and'will be more orless instantaneously anchored or secured thereon, thus eliminatingdistortion or displacement of the joints between plates, and of theplates themselves.

A still further object of the invention is the provision of an applianceby which an uneven or undulating surface can be covered with plates ofstructural material which will present an even, uniform surface.

More specifically, the invention contemplates an appliance in the natureof a container having a dished or depressed surface in which a body ofmastic will be retained, preferably by a number of perforations in saiddepressed surface, whereby mastic exuded through the perforations willkey or linterlock the entire body of mastic to the container. Ininstalling the structural plates, the appliances or retainers aresecured to the surface to be covered with the several retainers locatedin a common plane. A quicksetting mastic is then placed in the severalcontainers after which the structural plate is '1nstalled on themastic-filled containers.

Preferably, bodies of a more slowly setting mastic are also interposeddirectly between the covered surface and structural plates, but the morequickly setting mastic will secure the plates firmly in place to preventaccidental displacement of said plates until the more slowly settingmastic has set.

With th'ese and other objects in view, the invention consists in certaindetails of construction and combinations and arrangements of parts, allas will hereinafter be more full'y described, and the novel featuresthereof particularly pointed out in the appended claims.

In the accompanying drawing- Figure 1 is a front elevation of a surfacepar' Fig. 3 is a similar View on an enlarged scale;

Fig. 4 is a plan View of one of the mastic containers;

Fig. 5 is an edge View thereof;

Fig. 6 is a plan view of a modified form of container;

Fig. '7 is an end view thereof; and

Fig. 8 is a plan View illustrating a still further modification of thecontainer.

In installing the structural plates, whether they be of glass or othermaterial, a plurality of mastic holders or containers I0 are secured tothe wall or other surface Il, with the several containers all located ina common plane. As the plates are to be ultimately supported by thecontainers, it will be apparent that the plates, when installed, willpresent an even, uniform surface, regardless of depressions orirregularities that may be present in the covered surface II. In otherwords, the spacing of each container with respect to the particularsection or point of surface I I to .which it is attached will be suchthat all the retainers will lie in the same or common plane, regardlessof any unevenness in surface I I.

The several containers I0 should, preferably, be so placed on surface IIthat they will be located at the joints I2 formed between contiguousplates I3, the surface of each container preferably being such that itwill underlie portions of at least three plates. In installing theplates, the containers are rst secured in the surface II, as described,by nails I4 or other fastening elements, preferably driven in woodenblocks I5 embedded in the wall or surface. A quick-setting mastic I6 isvthen placed in the containers and the structural plates applied to thesurfaces of the mastic in a number of the containers, the several platesbeing usually applied with suicient pressure to position the surfaces ofthe several plates flush with one another. Usually, other bodies of acomparatively slow-setting mastic are also interposed between the platesand surface II, as indicated at I'I. Heretofore, it has been thepractice to use only the slow-setting mastic and, as a consequence, itquite frequently occurs that one or more of the plates will be displacedsomewhat before the mastic has set and anchored the plates. As a resultof this prior practice, open joints and uneven surfaces were a more orless common occurrence. The combined use of the quick and slow-settingmastics, with the latter at the joints, eliminates these diliiculties.

Preferably, the containers have a dished or concave surface to receivethe mastic and are formed with a plurality of apertures I8, so that whenthe mastic is pressed into the container, either at the time thecontainer is filled or when the plates I3 are applied, small incrementsof plastic Will exude through these openings and key or interlock themain body of mastic to the container.

Where it is desired to have the container span considerable distances,it may be made of elongated form as shown at |08 in Figs. 6 to 8. Thisform of container can be arranged transversely of any number of plates,as illustrated more or less diagrammatically in Fig. 8. Also, ifdesired, the elongated container |02* can be used in conjunction Withthe smaller, disc-like containers Il), the latter serving the purpose ofproperly spacing the members (a from the Surface to be covered. Such anarrangement is indicated in Fig. 7. The nail or other securing elementI4 is shown extending through both the containers in Fig. 7, but it willbe appreciated that member I 0a can be secured otherwise as, forinstance, by using mastic in container l0.

In each instance, the structural plates are firmly and quickly securedin place flush with one another, regardless of the contour of thesurface covered, and will remain in the positions in which theyT areinitially installed, thus eliminating danger of joints opening up orplates being displaced and thus misalined to destroy the evenness of theassembled plate surfaces.

What I claim is:

. 1. The method of installing plates of structural glass and likematerials to a surface to be covered thereby which consists in securinga plurality of perforated mastic retainers to said surface with saidretainers positioned in a common plane, filling said retainers with aquick-setting mastic under sufficient pressure to exude portions of themastic through said perforations, and applying the structural materialto the masticfilled retainers.

2. The method of installing structural plates of glass and likematerials to a surface to be covered thereby which consists in securingto said surface a plurality of mastic retainers with the severalretainers positioned in a common plane, filling said retainers with aquick-setting mastic, applying the Plate of structural material to themastic in said retainers, and interposing additional bodies of acomparatively slow-setting mastic directly between said surface andstruc- 'tural plate.

3. An appliance for securing plates of structural -material to a surfacein spaced relation thereto consisting of a perforated member having adepressed surface for supporting mastic therein at a point spaced fromsaid surface, and means for securing said member to said surface.

4. An appliance for securing plates of structural material such asuglassto a surface consisting of a member of sufficient area to overlieportions of each of a plurality of juxtaposed plates of said material,said member having means for supporting a body of mastic thereonindependently yof said surface, and means for securing said member tosaid surface.

5. An appliance for securing plates of structural material such as glassto a surface consistin'g of a member having a depressed surface ofsufficient area to overlie portions of juxtaposed plates of saidstructural material, said depressed surface having recesses thereinwhereby mastic pressed on to said surface will enter said recesses andbe interlocked to said member and means for securing said member to saidsurface With the mastic on the depressed surface spaced from the surfaceto which the glass plates are to be secured. y
